Aldo, greetings! Due to the technical nature of this question, I’ve shared it with the Canvas Developers group in the Community. You might consider joining this group to get access to their resources and information.

As I was taking another look at this issue, I noticed that in the canvas cloud hosted version by Instructure the launch link directed to

office365-iad-prod.instructure.com

But when I tried it out in the self hosted version of canvas it directed me to my Instances IP Address, however it still had the same path after launch but different domains. I was wondering could this be a problem where on the cloud hosted version it directs to office365-iad-prod.instructure.com but on the self hosted version it directs to the instances url.
